To aZZ whom it may concern Be it known that I, HANS S. Munari, aV

citizen of the United States,'residin at Racine, in the county of ERacine vand tate of lliisconsin, have'invented certain new and useful Improvements in Combination Ice Tanks and Hydraulic Scales; and AI do declare the following to be 'a 'full,'cl'ear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relat'esto improvements in combined ice tanks and hydraulic weighing scales.

One object of the invention is 'to provide means in combination With an ice tank whereby the specific gravity of the ice placed therein will be accurately indicated and the weight thus determined without the use'of springs, weights or like mechanicaldevices. Another object is to provide a device of this character which will be simple and inexpensive in construction and particularly adapted for use in connection with a refrigV erator. V A lVith these and other objects in view, the :invention consists of certain novel features of construction, combination andarrangement of parts, as will be more fully described and claimed.

In the accompanying drawings :--Fig"ure 1 is a perspective view of a refrigerator, showing my invention applied thereto; Fig. 2 is a vertical sectional view of the invention and a portion of the refrigerator; and Fig. 3

is a detail horizontal section of a 4portion of.

thc ice tank forming part of the invention.

In the embodiment of the invention, I provide a tank 1 having certain predetermined square dimensions and which is here shown and is preferably adapted to be arranged in a refrigerator 2. The tank 1 is preferably provided on its outer sides with series ofA laterally project-ing parallel ribs 3, and connected to one side of the samev near the bottom thereof is a fluid conducting tube Ll, which extends outwardly through the front side of the refrigerator and is turned upwardly and connected at its upper end with a glass gage tube 5 arranged on the outer side of the refrigerator', as` shown. In connection with the gage tube 5 is employed a scale plate G having arranged thereon a suitable graduated scale of weight, the purpose of which will be hereinafter described.

In one side of the tank at a suitable disthe water drained from the tank.

tance above the bottom thereof is a fluid discharge opening 7,'to which is connected ay iuid discharging tube 8 having on its upper end a valve casing 9, in which is 'arranged a valve 10.l The valve 10 is provided with a screw-threaded stern 11 having a-threaded 'engagement with an aperture in the valve4 casingl, and which is provided on its outer end with a' crankLhandle 12, whereby the valve may be shifted into and out of engagement with the opening 7 to close and open the latter. The lirst graduation or'the beginning of the weighing scale of the tube 5 is arranged directly opposite and in line with the bottom or lower side of the opening 7, so that when Huid is placed in the tank 1 and reaches said opening, theluid will seek its :level in the iluid conducting tube 4 and the lower end of the gage tube, this level-bev ing at the lower graduation or beginningof the scale, as will befreadily understood.

The tank 1 maybe provided with and is hereshown having in connection with it a drinking water tank 13 secured to or formed-integral with one side of the tank 1, whereby the ice in said tank 1 will cool the water in the tank 13; Connected with the lower end of the tank 13 is a discharge lpipe 14, which extends through one side of the refrigerator and has secured thereon afancet 15, whereby the water may be drawn from the tank 18 when desired.

In the operation of the device, water is placed in the tank 1 until the water reaches the level of and overflows through the opening 7 after which the valve i0 is operated to close said opening. The ice is now placed in the tank, whereupon the water `will be displaced or caused to-rise in the As the water 'is thus raised in tube 5 and the height of the water will be indicated by the scale 6, thus accurately deterrnining the weight of the piece of ice placed in the tank. After the weight` ofthe ice has been thus indicated, the valve 10 may be opened if desired and the greater part of From the foregoing description, taken in connectionwith the accompanying drawings. the construction and operation ofthe invention will be readily understood without requiring a more extended explanation.

and the minor (leiails of eons'ruciiion :may he resorted io without departing :from rhe principle or saeriieing any of the adven- 5 tages of this invention, as Claimed.

l-lafving; thus described my invention, what l claim is:-

A bank having therein at a suitable eleva-tien above the bottoni thereoB dis- 10 charge opening, a discharge cube eonneeised with said opening", a Valve casing on saidi tube, e, yalve arranged in seid easing; and adapted to be operated to close said opendag, a fluid conducting pipe eonneeed Wil-h the tank at the bottom thereof, and a gage tube Connected with said `'luid Conducting pipe and having in ooniieeion herewith a scale of Weight whereby the fluid displaced or raised in the tank by the specific gravity 39 of a body placed therein, will rise in raid tube and the speciie gravity or weight of the body placed in the tank thus indicated on the scale.

Q 2. in a refrigerator, an ice tank havinl therein at a suitable elevation above 13h bottom thereof a fluid discharging' opening, lai'erally-projeeting ribs forni-ed on the outer side of said tank, discharge 'tube Connected with said opening, a valve easing valve in said easing io open and close said opening, a threaded Stem on said valve having a vlhreaded engagement with said easa Crank handle on said stem, whereby the hitter is actuated to open and close the valve, a iuid conducting pipe with the rank at the botom thereof, and ,a glass gage Lube oonneeed with said fluid conducting "Cube and extending upwardly onA the outer side of the refrigerator to the height of said tank, said tube having in eonneeiion therewirh a. sealeof Weight beginning at a point on a level r`ith the opening in the tank, Wherehy when Said Valve iS Closed and a jie'ee of ice plaeed in the tank Jehe fluid thereiirwill be displaoed or raised to a height-corresponding with the Weight of the ice, said lduid rising;` in said tube to: al corresponding height, thereby indicating. on the scale of measurement the weigh or specilio gravity of he ice.

ln testimony whereof l have hereunto serl my hand in presence 01"' two subscribing Witnesses.
